The uraeus is the symbol of the sacred asp, used to decorate the headdresses of deities and pharaohs.

This weapon appears to have been modeled after either a real ancient Egyptian fan with no feathers, a Vulcan weapon called a lirpa, or after some of the weapons used by characters in Egyptian Hollywood movies such as The Mummy Returns. There has never been an actual Egyptian weapon that looks like this. The closest thing would probably be a Chinese monk's spade.
